我试图用设计1.3.4运行控制器规格. (和工厂女孩)
我按照git wiki中的说明进行了项目.我能够使用在宏中创建的login_user方法以用户身份登录,但login_admin失败并出现以下错误：

...
sign_in Factory.create(:admin)

Could not find a valid mapping for #<User id: 2023,email: "admin1@gmail.com",.... >

厂：

Factory.define :user do |f|
  f.sequence(:username) {|n| "user#{n}"}
  f.sequence(:email) {|n| "user#{n}@gmail.com"}
  f.email_confirmation {|fac| fac.email }
  f.password "a12345Den123"
  f.password_confirmation "a12345Den123"
#  f.admin 0
end

Factory.define :admin,:class => User do |f|
  f.sequence(:username) {|n| "admin#{n}"}
  f.sequence(:email) {|n| "admin#{n}@gmail.com"}
  f.email_confirmation {|fac| fac.email }
  f.password "a12345Den123"
  f.password_confirmation "a12345Den123"
  f.admin 1
end

控制器宏模块：

module ControllerMacros
  def login_admin
    before(:each) do
      @request.env["devise.mapping"] = Devise.mappings[:user]  #it should map to user because admin is not a model of its own.  It produces the same result either way.
      @admin = Factory.create(:admin)
      sign_in @admin
    end
  end

  def login_user
    before(:each) do
      @request.env["devise.mapping"] = Devise.mappings[:user]
      @user = Factory.create(:user)
      sign_in @user
    end
  end
end

路线

devise_for :users
devise_for :admins,:class_name => 'User'

一种解决方案是设置cache_classes = false,但这并不理想,因为我使用spork并且不希望在更改模型后重新启动它.

有帮助吗？

解决方法

我的路线中有这样的东西：

devise_for :accounts,:controllers => {:confirmations => "confirmations"} do
    put "confirm_account",:to => "confirmations#confirm_account"
    get "login" => "devise/sessions#new",:as => :login
    delete "logout" => "devise/sessions#destroy",:as => :logout
    get "register" => "devise/registrations#new",:as => :register
  end

所以在我的spec / support / controller_macros.rb中我需要改变：

def login_account
    before(:each) do
      @request.env["devise.mapping"] = Devise.mappings[:account]
      @account = Factory.create(:account)
      sign_in(@account)
    end
  end

至

def login_account
    before(:each) do
      @request.env["devise.mapping"] = Devise.mappings[:account]
      @account = Factory.create(:account)
      sign_in(:account,@account)
    end
  end

注意sign_in(范围,资源)

我希望这有帮助.
